SPECIFICATION forming part of Letters Patent N o. 682,120, datedSeptember 3, 1901.

Application iiled May 21, 1901. Serial No. 61,279. (No model.)

To all whom it may cc accru:

Be it known that I, JOHN W'. TOBY, a citizen of theUnited States,residing in the county of Richland and State of Ohio, have inventedcertain new and usefulImprovementsin Corn- Planters, of which thefollowing is a specification.

My invention relates to improvements in corn-planters; and the objectsof my invention are, iirst, to provide a means to check-row corn andobviate the necessity of stretching wires or cords across the eld tooperate the dropping mechanism, also to construct the device so thatit'can be used for either checkrow or drilling, and, second, to make acheap, durable, and eicient means for the purpose stated. These objectsI accomplish by the mechanism illustrated in the accompanying drawings,in which- Figure l is a top view of a check-row cornplanter, showingmyimproved mechanism for operating the attachment. Fig. 2 is a frontview with portion of frame broken away to show more fully theconstruction and arrangement of the parts constituting my improvement.Fig. 3 is a sectional View of portions 4 is a side View of the drivingsprocket-wheel.V

Similar letters of reference indicate the several parts throughout theseveral views. I

In the accompanying drawings, A indicates the frame, which maybe of anydesign or ordinary construction, as I do not wish to claim or describethe construction of the planter, but only the improved mechanism foroperating the dropping or planting devices now in general use. Y y

B is the front frame, upon which are secured the seed-receptacles C.

D and D' are brackets bolted upon the crossbars E and E', forming theframe B. The center of each bracket is provided with the boxings F andF, in which is journaled the shaft G. The said vshaft is placed centralbetween the rails E and F.' and is provided with the sprocket-wheel Hand the vertical flat disks I and I. The said wheel and disks aresecured rigid upon the shaft G. Each disk is provided with a ilat bar J.The said bars are provided with the cams K K', secured upon one end ofthe same. The said cams are wedge-shaped and are secured to the bars Jyloose upon the shaft. vided with any number of holes Z. The said and Jat right angles with the same. The bar J is secured rigid to the diskI', riveted or otherwise. The bar J is secured to the disk by the boltsL. The disk is provided with four holes, an equal distance apart,surrounding the circumference. The object will be fully explained in theoperation of the machine.

M and M are U-shaped brackets secured to the cross-rails E and E. Thesaid brackets are connected together by the metal bars N and N'. Thesaid bars are secured edgewise to the vertical walls of the U -shapedbrackets,

.one upon each side of the center, and are used as guides and upon whichrolls the rollers O,

bottom of the corn-receptacles by the bolts.

S and S.

Journaled upon the top of the connectingbar between the cams K and K arethe vertically-positioned rollers T and T. The said rollers rotate andovercome friction when the cams are operating the slides S.

Secured upon the axle V are the two iianged collars W and W', andbetween the said collars is placed the sprocket-wheel Y,

The said wheel is proholes surround the center. In the anged collar W isone hole which alines with the holes in the sprocket-wheel and in whichis placed a pin orspring-bolt A2 to lock the sprocket wheel'Y rigid withthe shaft. A sprocketchain B2 connects lthe sprocketwheels H and Y.

The accompanying drawings illustrate the machine connected to check-rowcorn. The motion of the shaft or aXle V conveys motion to thesprocketwheel H by the sprocketchain B2. The said motion rotates thecams K and K. The wedge-shaped cams come in Contact with the roller T',conveying a longitudinal sliding movement to the connectingbar Q andblock P. The weight of said bar and block is supported upon the track Nby the grooved rollers Q. In check-rowing the cams K and K are placed atthe inside and opposite ends of the .cam-levers J and J It will bereadily seen that when the machine IOS) is in motion the cam K willforce the dropping-slides within the receptacles to the right and thecam K to the left, causing a continuous reciprocating movement to thedropper -s1ides. Vhen the end of the field is reached, the pin A2 isWithdrawn, allowing the axle V t0 rotate and allow the droppingmechanism to remain stationary. When the machine is turned and broughtinto line, the pin is placed in position, and the machine is then readyto operate. When the operator wishes to drill in the corn, the bolts Lare removed. The cam-bar J is turned upon the shaft G one-quarter, so itwill be at right angles to the bar J and bolted rigidl to the iiange I.A cam 'is then secured upon the opposite end of each cam-bar. Themachine will then drop four times to every revolution of the shaft G.

Having fully described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-.

l. The combination with the frame and dropper mechanism, thedropping-slides connected together by a connecting-ban a block securedin the centerl and upon the under side sprocket-wheels and chain,substantially as set forth.

2. The combination with a main frame, axle, and supplemental frame forthe dropping mechanism, brackets secured upon the supplemental framebetween the dropping mechanisms, the said brackets supporting a shaft,the said shaft provided with flanged collars cam-levers secured to theflanged col'- lars wedge-shaped cams secured upon the end of saidlevers, a sprocket-wheel secured upon the shaft centrally between theflanged collars, the slides in the dropping mechanism connected togetherbya suitable connectingbar, a block secured in the center and upon theunder side of the connecting-bar, cam contact-rollers journaled upon thetop of the connecting-bar and block the block provided with a rollerupon the under side of the same, and adapted to travel upon a suitabletrackway secured in the supplemental frame between the droppingmechanism,the said meehanism operated by the rotation of the axlethrough sprocket wheels and chain, the sprocket-wh eel secured upon theaxle adapted to be engaged and disengaged at 'the will of the operator,substantially as set forth.

In testimony whereof I afiix my signature in presence of two Witnesses.

JOHN WV. TOBY.
